An HMV spokesman has confirmed to BBC News that METALLICA's new album "Death Magnetic" has gone on sale in the UK ahead of its planned September 12 release.Zavvi's flagship store on London's Oxford Street started selling it on Wednesday (September 10) while HMV also said it was now available in its stores. An HMV spokesman told BBC News: "We were advised yesterday by the label [Vertigo] that because it's been leaked quite heavily, they should bring forward its physical release and allow retailers to merchandise it. That was the communication we received and we've responded to that. I'd imagine it's a similar picture across the whole of retail." There is no suggestion that HMV or Zavvi broke the sales embargo. Music Week magazine reported that more than 2,500 copies of the album had been sold on CD by the end of Wednesday.
